2.5.1 Activating the technological function
The technological function is activated via the machine data:
MD60940 $MN_CC_ACTIVE_IN_CHAN_CLC[0], bit n = 1
n = channel number - 1; bit0 = channel 1, bit1 = channel 2, etc.
Note
The technological function can be activated for several channels simultaneously.
2.5.2 Configuring the memory
Memory configuration
The technological function requires additional data in the NCK-internal block memory. The
following memory-configuring channel-specific machine data must be parameterized:
• MD28090 $MC_MM_NUM_CC_BLOCK_ELEMENTS = x + 4
• MD28100 $MN_MM_NUM_CC_BLOCK_USER_MEM = x + 20
• 1) See note
Note
The values indicated must be entered in addition to the existing machine data value x.
